' Objects of the invention This invention relates to obstetricalappliances and has for its object to provide means for receiving,transporting and injecting sperm of the male to the female in cases ofartificial insemination, without exposing the semen to contaminationeither through contact with any article, air

normally held closed, but adapted to be opened at the moment ofejaculation, through the action of the greatest enlargement of the penishead, in order to receive the semen, which pocket will automaticallyclose tight upon removal from or contraction of said head.

A still further object of the invention is to provide a sack so formedthat sperm of the male may be collected, transported, diluted andinjected into the upper portion of the vagina, or directly into theuterus without exposure at any time to atmospheric or-any otherdeteriorating or contaminating influences.

Another object of the invention is to provide a method by means of whichartificial insemination may be accomplished without permitting the spermat any time coming into contact with air or any object through which itmay become deteriorated as to fertility, or contamination.

Another object of the invention is to provide a flexible (preferably anelastic) sack for the collection of semen and injection of the same intothe uterus of the female patient.

A still further object of the invention is to provide a sack forinjecting semen into the vagina of a female, said sack having meanswhereby the pressure may be brought to bear upon the sack withoutforcing it too far into the genital tract.

Another object of this invention is to provide a sack of the natureabove stated which is provided with automatic closing means at each endthereof.

7 With the above and other important objects in view as will hereinaftermore fully appear, I

2 have invented the device shown in the accom- D ying drawings.

orewo d I In the medical professionfphysicians have had to resort toartificial impregnation in many cases of sterility, due to variouscauses, such as malforination of the genital organs of either thebusband or the wife, infertility of the husband and many otherpathological reasons. In this practice it has been found that thespermatozoon becomes greatly weakened or killed through exposure tolight, atmospheric conditions or contact with bacteria infested organsor articles, which conditions have heretofore made it necessary torepeat insemination often many times, in order to bring about pregnancy.

It is extremely essential in this practice that the strictest rules ofasepsis should be carried 'out for success; otherwise, the semen maybecome contaminated with disease or other germs which will either resultin diseased offspring, or reduce the sperm to impotency.

It is'in order to overcome this probability of deteriorating thespermatozoon through the present unsatisfactory method of handling thesemen and the necessity of oft repeated injectionsincident thereto, thatI have designed the device to be hereinafter described.

In the artificial insemination of farm and other animals, which practiceis very common in Russia, Sweden, Switzerland and other Europeancountries, and which is a rapidly growing practice in the United States,the same difficulties in the collection, handling and injection of thesemen, as above outlined, has been encountered.

Practice has proven that semen may be collected (refrigerated whennecessary) and shipped for long distances without any materialdeterioration; however, it has been found that its exposure toatmospheric conditions, contaminated articles, or germ infested flesh,either of the veterinarian or the animal to be treated, often results ina negative operation, necessitating one or more repeated operationswhich result in much unnecessary expense unless such exposure isobviated, hence my invention. It is well known to practitioners in thisfield that the semen from one ejection is suflicient to bring aboutpregnancy in a number of difl'erent females, provided the semen issufficiently protected from deteriorating influences and is properlydiluted. My device makes provision for such dilution as will presentlybe explained.

Specification Like reference characters indicate like parts throughoutthe following specification and in the several views in the drawings, inwhich I indicates an artificial insemination sack formed of rubber, atreated fabric or other suitable material. This sack is of a size tosnugly fit the male organ and has provided at the outer extremity of itshead 2, a normally closed pocket 3. When the male organ head is swollento its greatest extent at the movement of ejaculation said sack head 2is stretched to such an extent as to open the aperture 4 whereby thesemen discharged will enter directly into said pocket. .Upon contractionof the male organ the rubber will automatically contract therewith,tightly closing said aperture and sealing the semen in said pocket.

Spaced inwardly of the end of the sackis another contraction of therubber, as indicated at H, which forms a normally closed mouth l2 forthe sack which mouth, however, will readily open upon stretching apartthe flaps l3 and I4 which terminate the outer end of the sack and extendbeyond said contracted mouth. 7

The extreme end 9 of the pocket 3 (as indicated particularly in Figure 4of the drawings) is greatly thinned in order that it may be readilyburst upon sumcient pressure being applied thereagainst.

Surrounding the sack l at a point inwardly of the apron I6 is a ratherthick flange i5, which forms a stop to limit the movement of the sackinto the vagina when the plunger 6 is used as indicated in Figures 2 and3 of the drawings. This plunger is preferably formed of semi-rigidrubber and is used especially in the impregnation of animals. Extendingfrom the flange l5 toward the members 13 and H is a relatively largeconically formed apron I 8 which forms the double function of a pocketwithin which the hand 'of a surgeon is slipped to grasp the portion I!of thesack therein for manipulating the same in an inseminationoperation in certain cases, and also as a hand grip to maintain holdupon the sack when the plunger 6 is being used in other cases.

The plunger 6 is provided with a concave recess l8 in the end thereofinto which the conweakened portion 9 I provide a non-elastic patch I9removably sealed, over said weakened portion which is adhered to thesurface 20 surroundentrance. vthe'extreme point 32 is weakened byremoving ing said portion 3 and which patch is provided with a loosetongue 2| by means or which it may be removed Just before theimpregnating operation. Instead of using this particular method offreeing the semen from its pocket, I may embed a thread 22 in thethinned portion 3, to be pulled out at the proper time. In this case thewall may be somewhat .thicker than the wall 9 but of a nature to nearlybreak through upon pulling upon the free end of the thread and tearingit from its place.

In cases of failure of natural insemination due to inability of spermcells to migrate to the cavity of the uterus because of cervicalobstructions of the cervix uteri, or cervical canal, stenosis in theregion of the internal os, etc., I have provided the form of deviceillustrated in Figure 7, in which the head 23 of snack 24 is providedwith an elongated probosci formed pocket 25 having a contraction 26 andweakened wall end 21, and which may readily probe its way throughcurvatures or obstructions to sufficiently close juxtaposition of theuterus to accomplish the desired purpose.

It is to be understood that instead of rubber the sack I may be formedof treated silk, or any other non-elastic material suitable for thepurpose in which the pocket 3 will be connected to the head portion 2 bya reduced neck within which is embedded an elastic band for contractingthe mouth 4. A similar closure may be provided at the mouth l2.

In Figure 8 I show another modification in which I provide a sack 28having a reduced neck 29 for the conical head 30 into which the semenis,directly ejaculated. Upon partial removal of the sack a string istied tightly around said neck to bottle up the semen and thus preventcontact with the air. This form of the invention is especially adaptablefor use for certain farm animals and poultry having a reduced externaloriflce to the genital canal into which the point 3| is inserted and theconical head then acts as a wedge to spread the flesh and therebyreadily gain Just before the entrance is started cap 33, to an extent topermit ready bursting through pressure.

Operation The operation of the invention is extremely simple and asfollows: The sack I is fltted to the male which is caused to make adischarge therein through any one of several well known devicesdisclosed by the U. S. Department of Agriculture or other satisfactorymethods. If after the sack has been removed from the male organ or penisand it is then desired to dilute the semenwhich has been collected isaid pocket 3. the mouth I2 of the sack is, turned up and the diluent ispoured in through a funnel, after which the pocket 3 is sufllcientlysqueezed to force the semen into the body portion 5 of thesack,.whereupon the sack is then sufficiently agitated to cause athorough amalgamation of the semen and diluent. After this is done asufficient portion of the mixture is squeezed back into the pocket 3whereupon the device is ready for impregnation of the female. Toaccomplish this purpose I provide the plunger 6, which is insertedagainst 15 stiiIen the sack and cause it to freely and easily 5 passinto the genital canal until its pocket end 3 has about reached theuterus, whereupon the sack is held by means of the apron l6 while saidplunger is pushed far enough into the sack as point II, to so expandsaid pocket through compression of its contents, to cause the extremelythinned or weakened center 9 to burst and let the contents of thepocketescape into or near the uterus. As soon as this escape occurs thepressure being relieved the pocket at once contracts and closes aperture4 hindering further escape of the sperm mixture. The bursting of saidpocket causes suflicient vibration to transmit the slight shock to thehand of the surgeon performing the operation who at once ceases pressureof said plunger.

Where there is a sufllcient quantity of the diluted fluid in the bodyportion of the sack the of sumcient size to permit the operator to holdthe sack in proper position and prevent the sack being shoved too far inthrough the action of the plunger, when used. In connection with thisoperation attention is called to the fact that due to the greatpliability and flexibility of my device, it may readily be causedtoenter and follow the genital tract toward the uterus and may be readilyused in case of lesions in the genital canals which preclude normalfecundation, resulting in sterility.

Method The method provided for by the above described invention is toobtain semen, retain the same until ready for use, transport the same toany desired distance (around the world if desired) dilute the semen(either atthe time of collection or at any period :before use) andinseminate the female, without at any time exposing the semen (fromcollection to insemination) to atmospheric, human, or any other contactwhich might contaminate, deteriorate or otherwise effect its potency.This is accomplished by soliecting the semen in the sack I and retainingthe same therein until discharged into the genital canal in theimpregnation operation.

It may be stated here that semen under proper conditions may bepreserved almost indefinitely. but according to physicians, expert inartificial insemination, veterinarians or general practice,

as well as those in the employ of the Department of Agriculture, agreethat no satisfactory method of preserving semen in its original purepotent state has heretofore been found.

In conclusion it may be stated that the invention will prove of thegreatest value to livestock breeders in the country due to the fact thatfemales may be bred from the finest male stock in the world at arelatively negligiblecost. And by the same method wives. with theassistease of their family physicians, may be inseminated with the semenof their husbands though "separated by half around the globe, thusavoiding the breaking up of countless homes.
